  • Ensure optical systems achieve stringent metric accuracy and signature data collection requirements for missile and space missions.
  • Provide independent technical assessment and recommendations on upgrades, risks, and technology roadmaps.
  • Support mission planning, real-time execution, and post-mission analysis with expert optical engineering input.
  • Inform CONOPS development and operational changes to optimize performance and resiliency.
  • Collaborate across radar, telemetry, and instrumentation teams for integrated mission success.
  • Track emerging optical technologies and assess applicability to RTS operations.

Required Qualifications:

  • Bachelor’s or Master’s degree in Optical Engineering, Physics, Electrical Engineering, or related discipline.
  • 7 years of relevant experience with advanced optical systems, visible/infrared sensors, or tracking instrumentation.
  • Proven expertise in optical system design, calibration, and performance characterization.
  • Strong systems engineering background with ability to assess requirements, readiness, and mission risks.
  • Experience working in joint environments with government, contractor, and laboratory partners.
  • Must be able to obtain and maintain a DoD Secret clearance.

Desired Skills:

  • Experience with test ranges, missile defense, or space tracking operations.
  • Familiarity with radar-optical integration and distributed control architectures.
  • Ability to lead technically without direct operational control of systems.
  • Strong communication and collaboration skills across multi-organization teams.
